Introduction
Jetty on OSGi consists of bootstrapping a standard jetty server from OSGi. It supports the deployment of traditional J2EE web-applications as well as web-applications contained inside an OSGi bundle (RFC66).
The goal of Jetty on OSGi is to offer a migration path for traditional J2EE applications to run inside an OSGi container. It favors J2EE applications currently deployed on jetty: developers and IT administrators familiar with a jetty deployment will found the same folder structure and configuration files.
Jetty-on-OSGi also provides an SDK for Eclipse-PDE that supports the development and debugging of a mix of traditional web-applications and web-applications contained in an OSGi bundle: Jetty on OSGi SDK for Eclipse PDE.
Feature
Jetty OSGi bootstrapping
A single bundle 'org.eclipse.jetty.osgi.boot' acts as an alternative to Jetty's Start.jar. It wires up all the jetty jars that can be located. It locates the ${jetty.home} folder where the configuration files are located. It starts a jetty server according to these configuration files:
It locates a ${jetty.home} folder (or generate one by default) and starts a jetty server according to the jetty.xml file.
The classloader inside which the jetty server is executing is a mix of the OSGi classloader provided by the 'org.eclipse.jetty.osgi.boot' bundle and also the jars and folders found inside ${jetty.home}/lib/ext and ${jetty.home}/resources.
The jetty.xml provided by default in jetty will deploy all web-applications found inside the ${jetty.home}/webapps and will read the jetty context files found inside ${jetty.home/contexts}.
